NK ClearNav Manual • Version 0.5 • July 3, 2008 We hope you find the ClearNav useful and that it increases your enjoyment of the wonderful sport of soaring. Please let us know if you have any suggestions for improving the product or the manual. 1.1 Contributors This manual was written by Paul Remde of Cumulus Soaring, Inc. (www.cumulus‐soaring.com) with help from many NK employees and ClearNav users. 1.2 Updates The latest version of this manual is available on the NK web site at http://www.nkhome.com/support/pdfs.html. 1.3 StepbyStep Directions Format This manual will use a basic “shorthand” method of presenting step‐by‐step instructions. This is done to keep the number of pages of the manual to a minimum so it is easy to print. Certainly, the detailed instructions below are very clear and easy to follow, but they use much more space than the Basic directions. Below are examples of Basic and Detailed step‐by‐step instructions. As you can see, the Basic version is much shorter, yet very clear. The Detailed version is shown here to clarify how to use the Basic version. The example below shows how to enable or disable the display of Bearing information in the Distance window. To toggle the display of bearing information on or off: Basic Instructions: Step through the instructions from left to right. Use the Up, Down, Left or Right buttons as necessary to select each item. The “/” character is used to clearly separate each step. Menu button / Setup Menu Icon Wind & Bearing / Bearing Checkbox To return to the moving map display – press the Menu or Focus button. This last step is not usually included in the basic instructions. / Personal Preferences Tab Page 10 of 86 / Map Display Options / ...

However, using a Macintosh to transfer waypoint, airspace, firmware upgrade and other files to the ClearNav is fine. File transfers are done using a USB Flash Drive which will work equally well in a Macintosh computer. Some “How To” sections in the manual give specific instructions with PC users in mind, but Mac users will find it easy to accomplish the tasks using their Macs. This manual does not attempt to give specific instructions for Mac users. 1.5 Important Notices 1.5.1 Before You Fly • Read the Manual Before you fly with the ClearNav, please read this manual while “playing with” a ClearNav unit on the ground. You will find the unit much easier to use and more enjoyable after you have taken the time to learn how to use it well.

Page 12: Fly Safely
NK ClearNav Manual • Version 0.5 • July 3, 2008 sections but also incorporates several real world tutorials which should help you get the most out of your ClearNav. Please don’t be intimidated by the large size of the manual. The manual includes many icons and graphics which help clarify things, but they take a lot of space – making the manual appear extra long. It is really a pretty quick and easy read. • Play with the ClearNav in Simulator Mode The ClearNav Simulator is a great way to play with the ClearNav on the ground. It allows you to fly the little glider on the screen around your local gliderport. You can turn, adjust the speed and even bump the altitude up and down using the remote control. We recommend taking it for a spin all the way around several tasks in the simulator before using the ClearNav in the glider. 1.5.2 Fly Safely It is very important to keep your eyes focused outside the cockpit as much as possible. Do not “play with” or configure the ClearNav while in flight. Learn to use the unit and configure it to meet your needs while safely on the ground. There have been several instances of very near misses (one glider nearly hitting another glider in flight) which were attributed to one or both pilots “playing” with their soaring flight computers or soaring flight software when they should have been keeping their eyes out of the cockpit looking for traffic. 1.5.3 Not a Certified Instrument The ClearNav is designed to enhance your soaring flight. It is not intended to replace your certified primary flight instruments. It is not a replacement for good judgment – which remains the responsibility of the pilot. All calculations are only as good as the data used in the calculation. If incorrect data is entered then incorrect information will be provided by the device. For example: If the glider polar data is not entered correctly the unit cannot calculate accurate final glide information. Also, the unit makes no attempt to warn you to avoid impact with the terrain – it assumes that you will see and avoid terrain and other aircraft. Waypoint and airspace data is the responsibility of the pilot. The ClearNav has no way of knowing whether the data in use is inaccurate or out of date. The maps displayed by the ClearNav are designed to supplement (not replace) the use of aviation maps such as sectional charts, etc. 1.5.4 Warranty This product is guaranteed to be free of defects in materials and workmanship for a period of TWO YEARS from the date of their first consumer purchase. NK will repair or replace any defective product or part when notified within the warranty period, and will return the product via domestic ground shipping at no charge. The following shall be excluded from warranty coverage: damage due to improper use or neglect (including corrosion); damage caused by severe or excessive impact, crushing or mechanical harm; modifications or attempted repairs by someone other than an authorized NK ...

NK ClearNav Manual • Version 0.5 • July 3, 2008 2.1.1 ClearNav Display The ClearNav “Display” is much more than a display. It includes: • Large and bright LCD display • Computer running the Windows CE.NET operating system. This operating system is similar to, but different from the Windows Mobile operating system used in Pocket PCs such as HP iPAQs. CE.NET can be thought of as the “industrial” version of the Windows Mobile operating system. • ClearNavigator soaring flight software • GPS engine and connector for external GPS antenna • Pressure sensor for altitude measurements • GPS Flight Recorder (IGC approval expected in 2008) • Built‐in SD memory card reader (in the side of the unit) • 2 RS‐232 serial ports for exchanging data with variometers, FLARM units, etc. The connections to the RS‐232 ports are on the Nexus Wiring Board • 2 CAN bus ports for connection to remote controls and 2 The connections to the CAN bus ports are on the Nexus Wiring Board. • USB Port for reading and writing to USB Flash Drive memory sticks There is one USB port on the back of the display and a remote USB port on the panel mounted CAN/USB Extension port – for easy access. • Size: 4.25"w x 5.83"h x 1.22"d (108mm x 148mm x 31mm) • Display Size: 3.39"w x 4.53"h (86mm x 115mm) • Screen Resolution: 240 x 320 pixels • Backlight: CCFL (Cold Cathode Fluorescent Lamp) backlight. Nominal luminance is 700 Candelas/m^2 (nits), achieved with a single lamp that goes around 3 sides of the LCD. NK provides lamp overdrive capability up to 1100 nits for severe ambient conditions such as flying ...

This increases battery drain, so the display is normally operated at its nominal luminance. • Weight: ~1 lb (450 g) • Memory: 2 GB of internal memory for turnpoint, terrain, map and airspace information • Power Input: 9 to 16 VDC • Power Consumption: 600 mA at full brightness, 300 mA at min. brightness, In power‐save mode the backlight goes to full brightness when any key is pressed on the remote keypad. It backs down to min. brightness about 25 seconds after the last key press. 2.1.2 ClearNav Handheld Remote The Handheld Remote is designed to be easy‐to‐use in flight – even when bumping along in ridge lift and wearing gloves. It offers 9 intuitive buttons that make it easy to quickly access any software feature. The Handheld Remote connects to the ClearNav Display through the panel‐mounted connector on the CAN/USB Extension. It can also be connected directly to either of the 2 small RJ‐22 connectors on the Nexus Wiring Board – but most customers will probably connect it through the CAN/USB Extension. Dimensions: 100 mm (3.9 inches) long x 44 mm (1.7 inches) wide x 24 mm (0.94 inches) deep 2.1.3 ClearNav Stick Mounted Remote The Stick Mounted Remote is made from precision carved mahogany with a durable two‐part epoxy finish. A 10‐button remote control panel is mounted in top of the handle for comfortable, ergonomic control of ClearNav with flying hand. It includes all the same buttons in the same locations as on the standard handheld remote. It includes a PTT (push‐to‐talk) button and wiring. The hole for the stick is customized to the stick diameter. Please specify the stick diameter when ordering. Page 16 of 86 ...

NK ClearNav Manual • Version 0.5 • July 3, 2008 2.1.5 ClearNav InPanel Mounting Kit The ClearNav In‐Panel Mounting Kit makes it possible to mount the ClearNav Display recessed into the panel for a very clean looking panel. Most installations done in new gliders will use this mounting method because it looks elegant. The kit included an yellow template to use when making the holes in the panel. In the photos above the yellow template is used as a stand‐in for the instrument panel ‐ to clarify which parts are on each side of the panel. Note: The SD card reader slot is mounted on the side of the ClearNav Display and is not accessible from the pilot side of the panel when the ClearNav In‐Panel Mounting Kit is used. That should not be a aluminum bezel, standoffs, support bracket and a Page 20 of 86 ...

NK ClearNav Manual • Version 0.5 • July 3, 2008 problem because a USB Flash Drive can be used for transferring files through the panel mounted CAN/USB Extension cable. 2.1.6 RAM Mount Kit In some gliders it is preferable to mount the display on a mounting arm that is attached to the instrument panel. This is the case when there is not enough room in the panel to mount the unit on the panel. When mounted on a mounting arm, the unit takes‐up less panel real estate. It is sometimes acceptable to partially block some instruments. Most customers will find that mounting the ClearNav directly on the instrument panel makes for a cleaner and classier installation than the RAM arm option, but those that prefer the RAM arm option will find that it is a rugged and reliable option. The optional 2 foot DB15 Extension cable is highly recommended for a neat installation. The Nexus Wiring Board is normally mounted behind the instrument panel with the DB15 Extension cable running from the ClearNav Display to the Nexus Wiring Board. The kit includes: • Short RAM "B" size arm with 1" balls and metal bases • Panel reinforcement plate and mounting hardware • Mounting adapter for attaching the RAM arm to the ClearNav Page 21 of 86 ...

NK ClearNav Manual • Version 0.5 • July 3, 2008 2.1.9 Panel Mounted CAN/USB Extension The Panel Mounted CAN/USB Extension brings USB and RJ‐22 connectors out to a convenient panel mounted connector. It fits into a 1" (25 mm) round hole in the panel. The USB connector is used as a receptacle for a USB Flash Drive for transferring flight logs from the ClearNav and uploading waypoint and airspace files and software updates to the ClearNav. The RJ‐22 connector is used by the Handheld Remote. A template is included for making the required holes in the panel. This item is included in the standard ClearNav system kit. 2.1.10 External Devices Page 25 of 86 ...
Page 26: Usb Flash Drive
NK ClearNav Manual • Version 0.5 • July 3, 2008 2.1.10.1 USB Flash Drive A USB Flash Drive is used to: • Transfer waypoint, airspace and other data files to the ClearNav • Download flight logs from the ClearNav • Upload firmware upgrades to the ClearNav USB Flash Drives are wonderful because they are simple to use and make it easy to transfer large amounts of data. When you plug one into your home computer it looks like a hard drive that you can transfer files to and from using the Windows Explorer (My Computer) program that is included with Windows. The ClearNav ships with a USB Flash Drive in the box with folders and files installed at the factory. If you prefer to buy an additional USB Flash Drive you can find one at any local computer store or Target, Best Buy, Radio Shack, etc. A 1 GB memory stick with was supplied with the first batch of ClearNav units and it seems to have plenty of memory. A 2 GB Flash Drive would hold all the maps, airspace, elevation data, etc. for the entire world. At the time of this writing $20 would get me a 4 GB Flash Drive on Amazon.com. It doesn’t hurt to get one that is larger than 1 GB. We recommend getting one in the 2 to 4 GB range, but larger is fine. 2.1.10.1.1 Transferring Flight Logs from the ClearNav to the USB Flash Drive At the end of the flying day you simply plug the USB Flash Drive into the ClearNav’s panel mounted USB connector and use the ClearNav’s Personal Preferences / Flight Recorder menu to select and transfer the desired flight logs from the ClearNav’s memory to the USB Flash Drive. 2.1.10.1.2 Transferring Files from the USB Flash Drive to the ClearNav When you want to transfer waypoint, airspace or software or firmware upgrade files to the ClearNav you simply power‐down the ClearNav, plug the USB Flash Drive into the ClearNav’s panel mounted USB connector, and power‐up the ClearNav. The ClearNav automatically transfers the files from the USB Flash Drive to the ClearNav’s internal memory. Page 26 of 86 ...
Page 27: Cambridge Aero Instruments 302
NK ClearNav Manual • Version 0.5 • July 3, 2008 2.1.10.2 Cambridge Aero Instruments 302 The Cambridge 302 is a great companion to the ClearNav. The following data can be received from the 302: • Vector Wind (speed and direction) • Real Time Headwind • True Airspeed from the 302 The Vector Wind (speed and direction) and Real Time Headwind can be displayed on the map screen. The Vector Wind is used for final glide (as the auto wind) if it is available. The wind information supplied by the 302 is a little more accurate and can be calculated when cruising as well as when circling by comparing the True Airspeed to the GPS measured speed and direction. Without the 302 the ClearNav calculates wind using wind drift while circling. To display the Real Time Headwind received from the 302 simply enable that option under Personal Preferences / Map Display / Wind and Bearing / Head wind Component. The 302 supplied True Airspeed is used for the total energy final glide computation. When not connected to a 302, the airspeed is calculated using the measured wind and ground speed. The Cambridge 302 can be connected to either of the RS‐232 serial port connectors on the Nexus Wiring Board. The Cambridge 302 to Nexus Board Cable can be used for the connection. It is shown below. A Y‐cable for connecting the 302 to both the ClearNav and a panel mounted connector for PDA or PC is also available from Cumulus Soaring, Inc. Page 27 of 86 ...
Page 28: Flarm
NK ClearNav Manual • Version 0.5 • July 3, 2008 2.1.10.3 FLARM FLARM is a collision alert system that is popular in many countries outside the USA. It has a built‐in GPS, pressure sensor and radio transmitter and receiver. It broadcasts its position and altitude so that other FLARM units in the area will be alerted to its presence. It gives alerts if a collision is predicted using data received from other FLARM devices in the area. The ClearNav can display FLARM data on the moving map display. The FLARM unit can be connected to either of the RS‐232 serial port connectors on the Nexus Wiring Board. The FLARM to Nexus Wiring Board Cable can be used for the connection. It is shown below. 2.2 Software The ClearNav runs ClearNavigator software that is specifically designed to work with the ClearNav’s unique remote control and other hardware. No other soaring software will work on the ClearNav system. The ClearNavigator software is designed to be easy‐to‐use in flight and intuitive. Yet it is very powerful software with many innovative features – such as the glide amoebae and the way it handles turn area tasks. 2.3 Data Files The ClearNav uses several types of data files for displaying map information, terrain elevation, airports and other waypoints, Special Use Airspace, etc. Fortunately, the ClearNav includes a large amount of memory so that it can hold map and terrain data for much of the world at once. It is important to make sure that the right data files are installed in the ClearNav so that you will have the best data available for your area. Page 28 of 86 ...
Page 29: Waypoint Files
NK ClearNav Manual • Version 0.5 • July 3, 2008 The good news is that the ClearNav supports several types of waypoint and airspace data files – to make it easy to find data for your area. However, there are some recommended file types. Using the recommended file types will allow the software to work at its best and display the largest amount of information. Any experienced pilot will tell you that sometimes it is best to limit the amount of information on the moving map. Just because it is possible to display vast amounts of data on the map at once does not mean that displaying everything will be a good thing. Sometimes it is good to hide certain types to data to limit the amount of screen clutter. Fortunately, the ClearNav makes it easy to enable and disable certain types of data when desired. 2.3.1 Waypoint Files Waypoint files consist of a list of navigation points to display on the map. There are several types of waypoints. They include airports, contest turnpoints, landing points (fields known to be good places to land when necessary), etc. The ClearNav supports waypoint files in the formats listed below. Links are provided to detailed data and example files for each file type. When transferring waypoint files to the ClearNav, put the desired waypoint files into the “Map Data” / “Waypoints” directory on the USB Flash Drive or SD memory card. The files will be pulled into the ClearNav upon start‐up. 2.3.1.1 Worldwide Soaring Turnpoint Exchange (.stx) files The best type of waypoint file to use in the ClearNav is the Worldwide Soaring Turnpoint Exchange format. It is highly recommended that you use this type of waypoint file whenever possible. If you use this format airports will display on the map with the runway shown with the correct orientation. We’ll call them .stx files. This waypoint file format is preferred over other compatible types because it can be extended easily to include types of data not supported in other waypoint file types. The great news is that .stx files are already available on the Worldwide Soaring Turnpoint Exchange for every soaring site listed there. Since the file is a simple tab separated text file, it is also easy to edit existing files manually, or create new files.

Description: http://data.naviter.si/docs/cup_format.pdf Example File: http://soaringweb.org/TP/Albert_lea/albert7c.cup 2.3.2 Airspace Files The ClearNav supports Special Use Airspace Files in the formats listed below. There is no advantage to either of the formats. They should both work equally well in the ClearNav. When transferring airspace files to the ClearNav, put the desired airspace files into the “Map Data” / “SUAs” directory on the USB Flash Drive or SD memory card. The files will be pulled into the ClearNav upon start‐up. 2.3.2.1 Tim NewportPeace (.sua) files This format is used by Glide Navigator II.

It is so important to soaring pilots around the world that it is hosted on 3 different web servers – which are all identical copies of each other. If one site doesn’t work for you, try one of the others. They can be accessed here: • http://soaringweb.org/ • http://soaring.xinqu.net/JL/ • http://soaring.gahsys.com/ 2.3.3.1 Downloading .stx Waypoint Files from the Worldwide Soaring Turnpoint Exchange To download .stx waypoint files for your soaring site, or an upcoming soaring contest site, follow the directions below. 1. Go to the Worldwide Soaring Turnpoint Exchange using one of the 3 links above. http://soaringweb.org is the main site. Note that there is no “www” in the link. 2. Click on the “Turnpoint Exchange” link found under the “Worldwide” heading. ...

NK ClearNav Manual • Version 0.5 • July 3, 2008 4 User Interface 4.1 Remote Control The handheld remote control is designed to fit comfortably into your hand and be simple and intuitive to use in flight. The 9 buttons on the remote are large and easy to press – even while flying in turbulent air, and when wearing gloves. They have a very positive click feel and sound which make it clear when a button has been pressed and released. They also stand out from the remote which makes them easy to find with your thumb without looking. The stick mounted remote control features the exact same pushbuttons as the handheld remote ‐ making it easy to switch between the 2 remote control types. Below is a quick overview of the operation and use of the 9 buttons on the remote. Page 34 of 86 ...
Page 35: Zoom In (+) Button
NK ClearNav Manual • Version 0.5 • July 3, 2008 4.1.1 Zoom In (+) Button The Zoom In (+) button is used to increase the zoom level of the moving map display. After zooming in you will see less of the moving map but will see it in more detail. To keep straight which zoom button to use ‐ think of the Zoom In (+) button as pushing the glider’s control stick forward to dive down closer to the earth. Since the Zoom In (+) button is located on the forward/top side of the remote – it makes sense – just push the forward button as if you were pushing the stick forward to get closer to the earth. The rectangular Selection Box in the middle of the moving map display shows the current zoom level. The scale number shown is the width of the rectangle. In the screen capture below (left) the scale rectangle in the middle of the map is 20 miles wide. If you were to press the Zoom In (+) button once you would zoom in on the map and the number in the rectangle would be 10 miles. Tip: When incrementing or decrementing numbers with the Up and Down buttons, the Zoom In (+) and Zoom Out (‐) buttons can be used to increment or decrement the value in larger steps.

After zooming out you will see more of the moving map but will see it in less detail. To keep straight which zoom button to use ‐ think of the Zoom Out (‐) button as pulling the glider’s control stick back to climb up away from the earth. Since the Zoom Out (‐) button is located on the back/bottom side of the remote – it makes sense – just push the back button as if you were pulling the stick back to climb away from the earth. The rectangular Selection Box in the middle of the moving map display displays the current zoom level. The scale number shown is the width of the rectangle. In the screen capture below (left) the scale rectangle in the middle of the map is 10 miles wide.

Page 38: Focus Button
NK ClearNav Manual • Version 0.5 • July 3, 2008 4.1.4 Focus Button The Focus button is used to toggle the focus between the Yellow Select Box on the moving map and the Numerical Information Area (NIA) on the bottom of the moving map. The term focus is used by software programmers to refer to the item on the screen that is currently active. The item with the focus is the active item. When the Yellow Select Box has the focus you can move it around on the screen using the Arrow buttons. When the Numerical Information Area has the focus you can use the Left and Right Arrow buttons to move through the displayed parameters. The use of the Focus button is intuitive because the yellow color of the button matches the yellow color of the item on the screen that has the focus. Changing the active item on the moving map using the Focus button. Shifting focus to any item on the screen is temporary. For example, the Numeric Information Area will lose focus automatically 25 seconds after your last key press. The Yellow Select Box will lose focus 5 seconds after your last key press. The Focus button also serves another important function. It can be used to exit the setup menus and return to the moving map display. The Menu button can also be used to exit any menu and return to the moving map display. 4.1.5 Select Button The Select button is used to “select” or “enter” or “OK” or “acknowledge” or “confirm” the current selection. It is located at the center of the keypad and is extended out further than the other buttons to make it easy to find and activate without looking at the remote. The round shape is different from all the other buttons – which also makes it easy to find and activate with your thumb. Page 38 of 86 ...

Page 41: Data At The Top Of The Screen
NK ClearNav Manual • Version 0.5 • July 3, 2008 4.2.1 Data at the Top of the Screen There are 3 data windows on the top of the moving map display. 4.2.1.1 Destination Window The Destination Window is located in the top left corner of the moving map screen and shows the name of the current destination. 4.2.1.2 Distance Window or The Distance Window is located in the top row of the moving map screen, between the Destination and Final Glide windows. It always displays the distance to the destination and can optionally display the both the distance and bearing to the destination. To toggle the display of bearing information on or off: Menu button / Setup Menu Icon Wind & Bearing / Bearing Checkbox 4.2.1.3 Final Glide “Altitude Differential” Window The Final Glide Window is located in the top right corner of the moving map display. The label “Alt. Diff.” (Altitude Differential) indicates that the number displayed is the difference between the altitude required to make it to the destination (taking into account wind, airspeed, glider polar, MacCready setting, etc.) and your current altitude. When you are above glideslope the number will be greater than zero and the box will be colored green. When you are below glideslope the number will be less than zero and the box will be grey in color. 1785 feet or meters (depending on units setup) above glideslope 390 feet or meters (depending on units setup) below glideslope Note on MacCready Setting Changes to the MacCready setting will lead to changes in the final glide altitude differential number. Increasing the MacCready number will indicate that you should be flying faster and have higher sink rates and therefore require more altitude to make it to the destination. Generally, new cross‐country pilots tend to bump the MacCready value down to zero when trying to decide whether they can make it home. Their reasoning is that if they fly more slowly they may be able to make it home. At first thought this seems like a conservative approach because they are / Personal Preferences Tab Page 41 of 86 / Map Display Options / ...
Page 42 NK ClearNav Manual • Version 0.5 • July 3, 2008 optimizing your glide angle. However, many more experienced glider pilots consider it to be less safe than leaving the MacCready number at a setting that matches the actual soaring lift conditions. The reason is that at a MacCready setting of zero you are at the ragged edge of making it home. You have no margin for error (or sink). You can’t slow down any additional amount to stretch your glide or speed up to get through sink. With the MacCready set to match the day’s soaring conditions the flight computer will recommend that you have more altitude before starting your final glide which will allow you to slow down to stretch your glide in the future if necessary or speed up in sink and still have enough extra altitude to make it home. In addition, you will arrive home more quickly. Total Energy Final Glide The ClearNav uses a feature called “Total Energy Final Glide” to take airspeed into account when calculating glide altitudes. When your speed increases the number in the Final Glide window will decrease because less altitude is required to make it to your destination – because you can pull up and gain some altitude at any time. When your speed decreases the number in the Final Glide window will increase because more altitude is required to make it to your destination – because you have less extra energy to convert into altitude.

The Left and Right buttons are used to move across the ribbon menu. The Select button is used to select the desired menu. To hide the Ribbon Menu press the Menu button or the Focus button . It is possible to wrap around from one side of the Ribbon Menu to the other side. For example, if you press the Left button while the Select Destination Icon highlighted. Not all of the icons shown below will be visible in the Ribbon Menu at all times. For example, the Simulator Icon is only displayed when in simulator mode. Also, the Ribbon Options Menu can be used to disable icons that you don’t use often. 4.2.2.1 Select Destination Icon The Select Destination Icon This is used mostly for “free flying” between waypoints – not when navigating through the waypoints in a pre‐declared task. It is also often used when flying a task, but low and in need of a nearby airport at which to land. Note that the Task Window move through the waypoints in a pre‐defined task.

When you fist enter the Select Destination window pressing the Left button repeatedly will toggle between the 2 tabs. Pressing the Right button once will move you from the Distance List Tab to the Alphabetical List Tab. Pressing it additional times will move the cursor (the highlighted character) through the alphabet list near the top of the window. Once the highlighted character has moved into the alphabet it is a little less intuitive how to get back to the Distance List Tab. You need to move the highlighted cursor past either end of the alphabet (past “A” or “Z”) – the Distance List Tab will then be selected – as if it was the 27 letter in the alphabet. The Up and Down buttons are used to move through the lists. The Zoom In (+) button can be used to jump up through the list one screen at a time. The Zoom Out (‐) button can be used to jump down through the list one screen at a time. Press the Select button to select he highlighted waypoint and start navigating to it. Selecting the Destination using the Selection Box For nearby airports it is much easier and faster to use the Selection Box to select them as the destination. Using the Selection Box is described here. 4.2.2.2 Bugs Icon The Bugs icon is used to access the bugs setting adjustment screen. If your glider’s wings are clean you would probably leave it set to the default of 100% clean. If you feel that you have picked‐up a significant amount of performance degrading bugs or water droplets, etc. you can lower the number to degrade the polar used for final glide calculations. The range of the % Clean setting is 60 to 120 percent and the default is 100%. When the Bugs icon is highlighted you can begin editing of the number by pressing either the Select , Up ...

The Show On Map window can be used to quickly and easily select the type of data to display on the moving map. Experienced contest and cross‐country soaring pilots would probably recommend keeping the information on the map to a minimum to reduce screen clutter and reduce the amount of time spent staring at the map – when your eyes should be looking out the window for traffic. However, there are times when the colorful data on the map is extremely useful and important. The best part is that it is easy to change the data to display in a few seconds while flying – so you don’t need to be too worried about how you set it up.

However, the colorful data can increase screen “clutter” and make it more difficult to see the data you need to see to fly the task – such as airports and airspace. Therefore, some pilots will opt to turn off the display of terrain data (especially when flying in flat regions) to improve the contrast of the display and to reduce screen clutter. • Culture Culture data includes cities and roads which are displayed on the map in shades of grey. As with Terrain data, some pilots will want to view the data to help them confirm that the cities and roads viewed out the window match the data displayed on the map. Others will prefer to turn off the Culture data to reduce screen clutter. It is very easy to turn the display of the Culture data on an off.

It is very easy to turn the display of the Water data on an off. It can be enabled and disabled independently of the Culture and Terrain data. • Landable Only The Landable Only checkbox is used to hide any waypoints that are not setup in the waypoint database as “landable”. It could be used when low to make it easy to view only airports or fields which can be used for landing. The default setting is unchecked – so that all waypoints will be displayed on the map, whether you can land there or not. Important Note: This feature is only as good as the data in the waypoint file. If the waypoint file has the “Landable” attribute assigned to airports that are not wide enough or long enough for your glider, you may have an “interesting” landing. It is your job to assure that the data in the waypoint file is correct. • Tracks The Tracks checkbox is used the enable or disable the display of glider tracks (“bread crumbs”) on the map. The tracks can be extremely helpful for re‐connecting with a lift source that was used minutes our hours earlier in the flight. Tracks are enabled by default. • Erase Tracks The Erase Tracks button can be used to erase all the flight track data displayed on the map. It does not affect the flight log data in the flight recorder. One situation in which you may want to erase the tracks is when the wind direction has changed significantly – making the circle tracks on the map from thermals earlier in the day useless. The Up and Down buttons are used to move through the options and the Select button is used to toggle the checkboxes on and off or to activate the Erase Tracks button.

NK ClearNav Manual • Version 0.5 • July 3, 2008 4.2.2.8 Simulator Icon The ClearNav Simulator is a great way to play with the ClearNav on the ground. It allows you to fly the little glider on the screen around your local gliderport. You can turn, adjust the speed and even bump the altitude up and down using the remote control. We recommend taking it for a spin all the way around several tasks in the simulator before using the ClearNav in the glider. The Simulator Icon is used to view the Simulator Controller. The Simulator Controller is used to make the glider in the simulator fly faster, slower, turn left or right, or to bump the altitude up or down. The image below shows the remote control features available in Simulator mode. The image on the left is shown on the map screen when editing the simulator settings. The image on the right was created to make it very clear what each button on the remote does while the Simulator Controller is displayed. The Simulator Icon is only visible when in Simulator mode. Simulator mode can be entered upon startup, or using the Menu button / Setup Menu Icon Tools Tab / Simulator button. When the Simulator Controller is visible on the screen you can adjust the glider’s speed, turn rate or altitude using the buttons on the remote control. When you adjust the turn rate or speed the current turn rate and speed will be displayed on the screen for a few seconds zero will make the glider fly straight ahead. A turn rate that is greater than zero will turn the glider to the right and a turn rate that is less than zero will turn the glider to the left. The turn rate is in degrees/second. Note that the simulator uses turn rates that remain in effect until you change the rate back to zero. That way you can set the glider up in turn and it will continue to circle indefinitely. Press the Zoom In (+) button to bump the glider’s altitude up by 100 m (328 feet). Press the Zoom Out (‐) button to bump the glider’s altitude down by 100 m (328 feet).

The Glide Wind Window is used to view or edit the wind speed and direction that are used by the software for final glide calculations. We’ll call the wind used for final glide calculations the Glide Wind. The ClearNav calculates wind speed and direction automatically using GPS data and measuring wind drift while circling. The ClearNav can also receive wind data from an external device such as a Cambridge 302, etc. The wind data provided by the Cambridge 302 is probably more accurate because it is calculated using airspeed data in addition to the GPS data – which ...

It can display several variometer values and is also used to display local time and set the UTC time offset and reset the variometer averagers. Vario Window Display Options The display options shown below are displayed in the climb units selected in the setup menus – such as knots or m/s. • Climb/Glide Netto This setting will display the Glide Netto in This Thermal while thermalling. The ClearNav switches between the 2 numbers automatically as you change flight modes – such as changing from Cruise to Climb mode or vice versa. There is a delay of a few seconds as you transition between flight modes because it takes a few seconds for the ClearNav to determine that you have changed flight modes. Climb Rate in This Thermal This is the average climb rate achieved in the current thermal. Glide Netto This is the average netto climb or sink achieved in the current glide. The term “netto” indicates that the sink rate at the current speed from glider’s polar is added to the raw vario number so that the displayed number shows what the airmass is doing rather than the combination of airmass motion and glider sink rate. A value of zero indicates that the glide has (on average) been done in still air. A positive value indicates that the glide has been done (on average) in rising air.

Page 59 NK ClearNav Manual • Version 0.5 • July 3, 2008 number to display most of the time as you “outsmart” the airmass. Example Calculation: As you cruise along on this glide the ClearNav is logging the difference between the current measured sink rate and the theoretical sink rate at the current speed from the polar. For example, for a single reading if the measured sink rate is 250 ft/minute and the polar gives a sink rate of 300 ft/min at the current speed then the netto value of +50 ft/min is recorded for this data point – indicating that the airmass is rising at 50 ft/min. The many numbers logged during this glide are averaged and the average is displayed. • Average Climb This is the average climb rate since take‐off – or since the start of the task. The number is automatically reset when the task is started because the data measured before the start of the task is likely to be very different from the data measured after the start of the task. Many pilots will find that this number is much lower than their best guess at their average climb rate. This number is theoretically a great number to use as a recommended MacCready setting. • Average Glide Netto This is the average netto climb or sink achieved in all glides since take‐off – or since the start of the task. The number is automatically reset when the task is started because the data measured before the start of the task (while trying for minimum sink rather than cross‐country speed) is likely to be very different from the data measured after the start of the task. The term “netto” indicates that the sink rate at the current speed from glider’s polar is added to the raw vario number so that the displayed number shows what the airmass is doing rather than the combination of airmass motion and glider sink rate. A value of zero indicates that the glides have (on average) been done in still air. A positive value indicates that the glides have been done (on average) in rising air. A negative number indicates that the glides have been done (on average) in sinking air. Theoretically, you will slow down in lift and speed up in sink and should be able to get a positive number to display most of the time as you “outsmart” the airmass.

The time To Finish is estimated by dividing the Distance To Go by the Predicted Speed. • Total Time The Total Time is the estimated time from start to finish to complete the task. It is calculated by adding the Time Since Start to the Time To Finish. This number is extremely useful when flying tasks that have a minimum task time. You may want to display this number when flying contest tasks. As long as the Total Time is longer than the minimum task time assigned by the contest managers, you are doing fine. If the Total Time is less than the minimum task time then you may need to fly farther into turn areas or add turnpoints to free tasks. • Distance To Go The Distance To Go is the distance from your current location around all remaining task turnpoints to the finish point. The units are the distance units selected in the setup screens – such as miles or kilometers.

It is shown regardless of which of the parameters you select for display in the Task Window. This is a fantastic feature! If you are displaying the Total Time in the Task Window it will show the total task time if you fly to the turnpoint shown on the map. The Total Task Time If You Turn Here is the total task time if you turn for home now. By comparing those 2 numbers to the minimum task time you will know exactly when to turn for home. We recommend waiting until the Total Task Time If You Turn Here is 3 to 5 minutes over the minimum task time – to make sure you make sure you don’t get home early. The screen image below should help clarify the 2 numbers. The time numbers are low in the example below because the simulator was blazing around the task at 1000 mile/hour. They will be in hours and minutes for real soaring tasks rather than minutes and seconds as shown below.

The only reason use the Start Now button would be if you wanted to start without going through the start gate or across the start line, or if you had started but for some reason (GPS issue..?) the ClearNav did not think you had started. Once the task starts the button changes from Start Now to Exit Task. The Exit Task button is used to exit the task if you decide to re‐start or abandon the task. • Next Leg / Turn Here? Button The Next Leg button is used to move on to the next leg of the task. For example, if you are currently navigating to the first turnpoint and have just rounded the turnpoint you would press the Next Leg button to tell the ClearNav to start navigating to the next turnpoint in the task. The ClearNav will automatically switch to the next leg when you enter the turn cylinder of an assigned task, but it will not automatically switch when flying an area task – because you will probably want to continue flying into the turn area rather than moving on as soon as you enter the turn area. The button changes to a Turn Here? button when you enter into a turn area. When you select the Turn Here? button the task is redrawn with that point as the turnpoint and the active waypoint is changed to the next waypoint in the task. After the Turn Here? button is pressed, it turns into an Undo Turn Here button. Select the Undo Turn Here button to resume navigation to the calculated ideal turnpoint. • Resume Task Button The Resume Task button is used to resume the task after it has been suspended. The task is suspended any time you start navigating to a non‐task turnpoint. For example, if you are getting low and use the Selection Box to fly to a nearby airport, the task will be suspended. When the Resume Task button is pressed the ClearNav will resume navigating to the waypoint that it was navigating to when the task was suspended. • Glide To Finish / Glide To Next WP Button The Glide To Finish button makes it possible to display final glide information around multiple turnpoints to the finish. The ClearNav will continue navigating to the current task turnpoint, but the Final Glide Window turnpoint. It will display the final glide around the remaining task turnpoints to the finish. Also, the Distance Window change in the text description in the Final Glide Window – instead, the Destination Window changes to “To Finish” point. The other indicator that you are displaying the Glide To Finish number in the Final Glide Window is that the Glide To Finish button will change into the Glide To Next WP (waypoint) button. Press the Glide To Next WP button to resume displaying the final glide and distance to the active task waypoint. • Achieved Speed ...
Page 65 NK ClearNav Manual • Version 0.5 • July 3, 2008 important to remember that the Achieved Speed will probably be quite a bit slower than the speed you attain during the remainder of the task. That is because you will not be stopping to thermal when on final glide which will make your average speed go up significantly for the last part of the task. The Predicted Speed automatically takes the final glide into account making it unnecessary to try to use the Achieved Speed to manually calculate the speed for the remainder of the task. Page 65 of 86 ...
Page 66 NK ClearNav Manual • Version 0.5 • July 3, 2008 • Using Auto / Using Manual Button The Using Auto / Using Manual button is connected to the Predicted Speed values that are displayed below it. When it is highlighted press the Select button to toggle between manual and automatic calculation of the Predicted Speed. The default is Using Auto. The ClearNav always automatically calculates Predicted Speed using your climb and glide performance to this point and taking into account the final glide portion of the flight during which the average speed will increase because you won’t be stopping to thermal. The automatically calculated speed is always displayed on the far right edge of the screen. The manually entered number is displayed in an edit box to the left of the automatically calculated number. In Using Auto mode the calculated speed is automatically bumped into the “manual” speed position. When in Using Manual mode the calculated speed can be used as a reference and you can manually set the Predicted Speed. Most pilots will probably use the Using Auto mode most of the time. A good example of when it makes sense to manually enter the predicted speed is when you know that you will be flying much faster or slower for the remainder of the task due to changes in the weather or type of soaring flight – such as a cloud street or isolated storm up ahead or a transition to ridge running or wave flight. When it Using Auto mode, manually editing the Predicted Speed will change the mode to Using Manual mode. Page 66 of 86 ...

Altitude Display Options • Altitude MSL (Mean Sea Level) The Altitude MSL is the altitude that has been adjusted to compensate for changes from the standard atmosphere. You can and should edit the Altitude MSL before takeoff every time you fly by setting it to match the known airport elevation. This number is the one used for the final glide calculations – so be sure to set it before takeoff. The Altitude AGL (below) is based on the MSL Altitude so it will only display accurately if the MSL Altitude is set accurately. You can easily use a local automated weather transmitter (AWOS) pressure setting to adjust the MSL Altitude in flight. • Pressure Altitude The Pressure Altitude is the raw altitude from the pressure transducer and shows the altitude in a standard atmosphere. Since the local barometric pressure is not likely to match the standard atmosphere this number will be different than the MSL Altitude. This number is used when near special use airspace such as when near 18,000 feet in the USA. • Altitude AGL (Above Ground Level) The Altitude AGL is the approximate altitude above ground level. This is a very powerful feature because it makes it easy to know your approximate altitude above the terrain at a glance. You will find the Altitude AGL especially useful when flying in mountainous areas. Of course, the elevation model is not perfect, so don’t count on this number to warn you about local objects that stand up above the general terrain elevation. The MSL Altitude is used to calculate the Altitude AGL so it is important to set the Altitude MSL before takeoff. The Altitude AGL is calculated by subtracting the ground elevation (from the built‐in ground elevation model) from the Altitude MSL. or or ...

NK ClearNav Manual • Version 0.5 • July 3, 2008 Press the Focus or 4.2.4.3 Create a Mark Point A Mark Point is a waypoint that is created using the Selection Box. If you have not moved the Selection Box the Mark Point will be created at the current location of the glider. If you have moved the Selection Box is created at the location of the cross‐hair (“+”) at the center of the Selection Box. It is often used in flight to mark the location of a good thermal so you can find it again in the future. It can also be used to create points before flight. However, Mark Points do not appear on the list of waypoints used for creating tasks – so it is not possible to create a task using Mark Points. Every time you add a new Mark Point it is saved into the current waypoint file so that it will appear the next time you fly. Each new Mark Point is given a new name – such as ”Marked Point 1”, “Marked Point 2”, etc. The only way to delete a Mark Point is to copy the waypoint file to a PC and edit the waypoint file manually. There may be a way to delete a Mark Point using the ClearNav in the future. To create a Mark Point: Press the Focus button once or twice until the yellow box is displayed around the Selection Box Use the Up , Down desired turnpoint.

Page 76: Glide Amoebae
NK ClearNav Manual • Version 0.5 • July 3, 2008 4.2.5 Glide Amoebae The Glide Amoebae (plural form of Glide Amoeba) are powerful graphical display items which make it obvious at a glance how far you can glide in any direction. Any airport or field that is inside the Glide Amoebae is within glide range. There are 2 Glide Amoebae displayed on the map. The arrival altitudes for each Glide Amoeba are adjustable. There is also an optional MSL Altitude Glide Ring which is described in the next section. Example showing the Glide Amoebae in mountainous terrain As you can see in the image above the Glide Amoebae can take on strange “amoeba‐like” shapes when flying in mountainous terrain. The purple Glide Amoeba has a flat spot on the top left side where a mountain ridge is located. The points where the Glide Amoeba shoots out (such as at the left side) is where there is a mountain pass that can be glided though and on into the valley beyond. Page 76 of 86 ...
Page 77 NK ClearNav Manual • Version 0.5 • July 3, 2008 Example showing the Glide Amoebae in flat terrain In flat terrain the Glide Amoebae are simple circles that are offset by the wind. The Glide Amoebae’s location is calculated using: • The glider’s polar • The wind speed and direction • The glider’s MSL Altitude • The elevation of the surrounding terrain • The glider’s airspeed – The final glide calculations are based on total energy final glide. As you fly faster your glider has more energy and could pull up to gain altitude and range. For example, if 2 identical gliders were at the same location and altitude but different airspeeds, the one at high airspeed would have more energy and could pull up to gain more altitude. Therefore the Glide Amoebae for the glider at high speed would be displayed farther away from the glider than the Glide Amoebae of the glider at lower airspeed. To access the settings for the Glide Amoebae go to: Menu button / Setup Menu Icon / Personal Preferences Tab Page 77 of 86 / Final Glide Settings ...

Page 79: Msl Altitude Glide Ring
NK ClearNav Manual • Version 0.5 • July 3, 2008 4.2.6 MSL Altitude Glide Ring The MSL Altitude Glide Ring can be displayed on the map to show how far you can glide descending down to the user selected MSL Altitude. This option is a neat idea, but we aren’t sure yet how useful it will be. If you don’t use it we recommend turning it off to limit the amount of information on the map. In still air you can glide from your current location all the way to the MSL Altitude Glide Ring. You will arrive at the ring at the user selected MSL Altitude. The ring will only display when the glider is at an altitude that is higher than the user selected MSL Altitude entered for the MSL Altitude Glide Ring. As you increase the number entered in the MSL Altitude the ring will get closer to the glider because the difference in altitude will get smaller. The MSL Altitude Glide Ring may be useful is when trying to overfly an airspace region. For example, if there is airspace nearby that has a ceiling of 3000 feet MSL, you could set the MSL Altitude Glide Ring to 3000 feet (or 3200 feet to be conservative). If the airspace you want to fly over is completely inside the MSL Altitude Glide Ring then you know that you can glide over it. If the airspace region extends beyond the MSL Altitude Glide Ring then you know that you can’t make it all the way across the airspace region without descending down into it. Page 79 of 86 ...

When you plug the USB Flash Drive into your computer the computer should recognize the drive in a few seconds and give you the option to view the files. Windows will open the Windows Explorer (My Computer) program and display the files on the USB Flash Drive. You can then copy the files onto your computer’s hard drive. We recommend copying the flight logs into a “My Documents/Flights” folder. 5.2 Transferring Waypoint and Airspace Files from the PC to the ClearNav A USB Flash Drive is used to transfer files from your home or laptop computer to the ClearNav. You will want to transfer waypoint and airspace files for your region to the ClearNav before using it for the first time, and every time you bring it to a new soaring site. The ClearNav can store waypoint and airspace files for many soaring sites in its internal memory. Creating or downloading waypoint files and airspace files is covered in the Waypoint Files and Airspace Files sections. 5.2.1 Transferring Waypoint and Airspace Files from your Computer to the USB Flash Drive ...
Page 82: Transferring Waypoint And Airspace Files From The Usb Flash Drive To The Clearnav
NK ClearNav Manual • Version 0.5 • July 3, 2008 You can then copy the files from your computer’s hard drive onto the USB Flash Drive. Waypoint files should be copied into the “Map Data/Waypoints” directory on the USB Flash Drive. Airspace files should be copied into the “Map Data/SUAs” directory on the USB Flash Drive. The files need to be in those directories for the ClearNav to access them. 5.2.2 Transferring Waypoint and Airspace Files from the USB Flash Drive to the ClearNav Transferring the waypoint and airspace files from the USB Flash Drive to the ClearNav is very easy. 1. Plug the USB Flash Drive into the ClearNav’s panel mounted USB connector 2. Power‐up the ClearNav. The ClearNav automatically transfers the files from the USB Flash Drive to the ClearNav’s internal memory. 5.3 Upgrading the Firmware and Software in the ClearNav The term Firmware is used to describe the software that runs the operating system and hardware drivers in the ClearNav. The term software will be used in this manual when referring to the actual ClearNav application. The term firmware was created to clarify that the software is pre‐installed by the manufacturer. A decade or 2 ago firmware was usually programmed into a memory chip at the factory. But today firmware and software can often be downloaded from the internet and transferred to a device to give it new functionality. That is an advantage for those of us using the products because we can upgrade them in a few minutes without the need to send the unit back to the factory for an upgrade. You do not need to worry about which files are firmware and which are software. You only need to download new files to the USB Flash Drive and the ClearNav will automatically pull in the files it needs. To upgrade the firmware and/or software in the ClearNav you need only a USB Flash Drive. 5.3.1 Downloading the Firmware and Software Upgrade Files to your Computer ClearNav firmware and software upgrade files will be available on the NK web site. Download the files to your computer. They will probably be saved in a Zip file. Unzip the files directly into the root directory on the USB Flash Drive. The root directory is the highest level directory. 5.3.2 Transferring Firmware and Software Files from the PC to the USB Flash Drive Unzip the files directly into the root directory on the USB Flash Drive. The root directory is the highest level directory. To unzip the files click on the zip file. Select all the files in the list and click the “Extract” button. A window will appear for you to select the destination for the extracted files. Select the root directory of the USB Flash Drive as shown below and press the “Extract” button. Page 82 of 86 ...
